Capatect IDS Meistermörtel

Substrate Preparation

Fixing of Capatect IDS Mineral boards:
Masonry, concrete or adherent existing coatings must be clean, dry, sound/stable, and free from all substances, that may prevent good adhesion, e.g. formwork oil residues. Remove mortar burrs and unsound, flaking/peeling existing paint and textured render/plaster coatings as far as possible. Cut off render/plaster with local separations having no sufficient adhesion to the substrate and repair to match the surrounding surface. Clean highly absorbent, sanding or chalking surfaces thoroughly up to the solid substrate level and prime with Sylitol-Konzentrat 111.

The wall must be protected against ascending moisture. The wall surface must be protected against driving rain through leaks and pores in accordance with the valid requirements. If necessary, protect by appropriate measures. A full-surface bonding of the IDS insulation boards must be ensured.
Wall anchors:
On suitable substrates with good mortar adhesion the insulation systems IDS Mineral and IDS Protect do not need additional anchors.
Primer:
A primer is usually not required.
If the assembled IDS Mineral and IDS Protect boards have to be smoothed widely, they can be primed with Sylitol-Konzentrat 111 to fix sanding dust.
Reinforcement layer:
Uneven misalignment in flatness of Capatect IDS Mineral insulation boards must be sanded prior to the application of the reinforcing layer and then cleaned of the sanding dust.

Method of Application

Fixing the IDS insulation boards:
The reverse side of the insulation boards must be covered with Capatect  IDS Meistermörtel with a  square-notched  trowel over the entire area (horizontally toothed). Notch depth and mortar quantity must be adapted to the roughness of the wall. Small unevenness can be compensated. Larger unevenness must be applied to the substrate by gluing in the floating-buttering process. For that apply a vertically notched mortar bed on the wall additionally. The IDS insulation boards are to be placed horizontally staggered on the wall from the bottom to the top, floated with slight pressure with a lateral displacement of approx. 2 cm. Avoid open joints. The adhesive mortar must not be introduced into the board joints. The IDS insulation boards must be installed in a plumb-vertical and flush manner. A full-surface bonding of the boards must be ensured.
A separate decoupling strip (IDS Hemp Wool Insulation Strip) should be used to separate connecting components, such as wooden floors and wooden beam ceilings, which allow different stretching behavior and setting.

Reinforcement layer:
After applying the IDS Thermowinkel (thermocouple) along the embedding wall and ceiling components as well as the corner protectors at edges and corners, the IDS Meistermörtel is to be applied to the IDS insulation board in appropriate layer thickness in the width of the IDS Armierungsgewebe (reinforcing fabric). Then embed the IDS Armierungsgewebe into the fresh mortar with approx. 10 cm overlap and smooth the surface. A total layer thickness of approx. 5 mm must be achieved. Take care that the IDS reinforcing fabric is fully embedded and lies in the outer third of the reinforcing layer.

Render:
To achieve a wet smoothed  top plaster, apply IDS Meistermörtel to the existing substrate in a thickness of approx. 2 mm. In the hardening process of the mortar, the surface can be smoothed with a moistened sponge trowel.
Note: On wet smooth surfaces, a fine shrinkage can not be completely ruled out due to superficial laitance layer (binder enrichment). This does not constitute an objectionable defect.

Consumption

Application Conditions

Drying/Drying Time

At 20 °C and 65 % RH: surface-dry after approx. 24 hours. Additional anchoring of the insulation boards can be carried out after sufficient consolidation of the adhesive bed - after curing for at least one day.
Cured, recoatable and ready for stress after 1 to 2 days. Before a further coating work of the reinforcing layer, a waiting time of 1 day / mm of layer thickness is generally required (depending on temperature and relative humidity).

Tool Cleaning

Immediately after use with water.

Material Preparation

IDS Meistermörtel can be used with all types of flow mixers or screw pumps and suitable machine equipment for render and plaster application. If manually applied, pour the powder slowly into cold tap water and stir up with a suitable low-speed electric paddle until the mixture is free of lumps. Leave to stand and swell for approx. 5 minutes and stir up again. Adjust to working consistency by adding a small amount of tap (potable) water, if necessary.

Water requirement: approx. 5 - 6 l per 25 kg bag. Workability and pot life depend on weather conditions: In case of manual material preparation approx. 2 hours; in case of mechanical conveyance max. 60 minutes. Never mix slightly hardened or stiff material with water - such material is unusable.

Note

For the application and execution see DIN 18550, as well as in Germany DIN 18350, VOB ,part C.

Special Risks (Hazard Note) / Safety Advice (Status as at Date of Publication)

The mineral powder interacts with water to an alkaline reaction and should only be used by trained operatives. Causes skin irritation. Causes serious eye damage. May cause respiratory irritation. Keep out of reach of children. Wear suitable protective gloves, goggles and face protection. Do not breathe dust. Do not get in eyes, on skin, or on clothing.  IF IN EYES: Rinse cautiously with water for several minutes. Remove contact lenses, if present and easy to do. Continue rinsing. Contains potland cement.

Disposal

Materials and all related packaging must be disposed of in a safe way in accordance with the full requirements of the local authorities.
Particular attention should be made to removing wastage from site in compliance with standard construction site procedures.

In Germany / EC:
Only completely emptied bags should be given for recycling. Hardened material
residues should be disposed of as mixed construction and demolition waste.
